我有一台 WD MyBook 320GB。Windows 和 Linux 都可以看见该设备，但无法识别它。
$ lsusb
Bus 002 Device 017: ID 1058:0910 Western Digital Technologies, Inc. MyBook Essential External HDD
$ sudo fdisk -l
fdisk: cannot open /dev/sdb: Input/output error
当我使用 fdisk 命令时，我听到来自磁盘的周期性声音，就像重试错误一样。
我还给出了 dmesg 的一部分：

我正在考虑拆开外壳，看看能否通过使用 SATA 电缆连接磁盘来获得任何东西。您认为这有意义吗，或者重试错误只能由磁盘本身的故障引起，而不是外壳/USB 连接器？
还有其他建议可以挽救我的数据吗？
编辑：
我已经打开了磁盘，USB 连接器可以很好地与其他磁盘配合使用。但是，我设法使用另一个连接器查看我的磁盘，Windows 显示未分配空间，fdisk 显示：
Disk /dev/sdb: 298.1 GiB, 320072933376 bytes, 625142448 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
您建议使用哪些工具来帮助我恢复至少部分数据？
答案1
- 从塑料盒中取出磁盘并直接连接。看看会发生什么。
- 如果您仍然看不到驱动器，请购买与捐赠者相同的 HDD 型号（来自 eBay？）并更换电子设备。
我已经做过几次了，效果很好！我还建议使用 SpinRite 在磁盘旋转时恢复数据。
请勿打开驱动器本身！仅更换电子产品！
